The Genie 990820GT Hex Head Cap Screw is a genuine OEM fastener designed for AL5000, RL4000, and TML-4000 light towers. As a direct Genie OEM part, this screw is manufactured to the exact thread specification and grade called out in the original parts manual — no guesswork on sizing or material grade. Cross-reference part number 990820GT against your machine's parts manual to confirm this is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Material and Thread Accuracy — Manufactured to the 1/2-13 X 2 thread specification and grade rating called out for these machines, ensuring correct clamping load and thread engagement.
- Direct OEM Replacement — Installs directly in place of the original fastener with no modification, matching the hex drive size, thread pitch, and length exactly.
- Confirmed Fitment — Genuine OEM fitment for Genie AL5000, RL4000, and TML-4000 light towers; always verify against your unit's parts manual before ordering.
- Structural Integrity — A correctly torqued, properly graded fastener holds assemblies securely under load and vibration. A stripped, corroded, or incorrectly specified screw can allow joints to loosen, creating operational risk on a working light tower.
- Sourced Directly from Genie — Supplied as a genuine Genie OEM part through DHS Equipment, ensuring you receive the correct part with the correct grade designation.
A hex head cap screw is a structural fastener used to clamp and secure assemblies throughout the machine. The 1/2-13 thread designation refers to the screw's diameter and thread pitch, while the grade rating governs the tensile strength and clamping force the fastener can reliably deliver. Using a fastener of the wrong thread, length, or grade risks under-clamping or damage to threaded bores — both of which can cause assemblies to work loose during operation. Replacing a worn or damaged screw with the correct OEM-specified part restores the joint to its original holding strength.
